IMPRWOVEMENT IN HARVESTERS. A

Specification forming part ofA Letters Patent No. 10.671, dated March 2i, 1854.

To all whom it may concern Be it known that I, PHILIP H. KELLS, Yof Hudson, in the county of Columbia and State of New York, have invented a new and use-V ful Improvement in Mowing-Machines; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, forming part of this specification, in which- Figure 1 is a side elevation of the machine. Fig. 2 is a plan of the same.

bimilar letters of reference in the several tignres indicate the same part of the machine.

The object of this invention is to give the cutter-bar of my machine such a position as will cause the cutter or knife to conform to thek The invention consists in so plaoin g the knifeframe that the bar to which the cutting-blade is attached shall be in a range with and perpendicular to the side of the guiding-roller when the axis of that roller is parallel to the axis of the driving-Wheel.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

ln the drawings, A is the driving-wheel, having on its side face the cogs a, into which meshes the pinion B on the shaft C. On the rear extremity of the shaft C is the wheel b,

meshing into the wheel c on the shaft D,which` connecting the eccentric with the cutter-har n.v

rIhis arrangement, which is not arbitrary, may be replaced `by any equivalent mechanical device.

E is the guiding-roller, placed directly in front of the driving-wheel, and pivoted to facilitate the turning ofthe machine. The draftbar F is infront of the roller, and the line of draftin the prolongation ofthe wheel and roller.

The knife-frame H is on the gearing side of the machine, and is attached to the gear-frame I by the brace h. To this frame are attached the guard-teeth t', through which reciprocates the bar n, carrying the knife fm, said bar being connected with the rod]` by the joint l. The

'which holds the cutter m, shall always range with the roller E and be perpendicular to its side when the axis of the said roller is parallel to the axis of the drivingwheel, for objects which will be hereinafter set forth.

The operation of my machine is as follows: The forward motion of the driving-wheel A produces a reciprocating motion of the knife m under the frame H and in the slots of the teeth 'i by reason of the connectingrodf, eccentric d, shafts C and D, pinion B, cogs a, and cog-wheels Z and c. The placing of the cutter-bar a so as to range with the roller E when its axis is parallel to the axis of the driving-wheel enables the machine to operate with perfectregularity,notwithstandingthe uneven surface upon which itis worked, as the cutterbar will always runthe same distance from the surface of the ground, its vertical movements being so governed by the guiding-pulley as to have the same rise and fall as that pulley at the same time. This is of great importance, as any position other than that here given would interfere materially with the operation of the cutters when running across water-furrows and other inequalities, for when the pulley would be in the trough of the furrow the 'cutters would be thrust into its forward side and be broken or bent in the rise of the machine, whereas in my machine the bar n will in that case be at the constant distance from the bottom ofthe furrow, and, rising with the revolution of the pulley,`will preserve the same distance from thc surface of the ground and carry the cutters clear of the sides of the furrow. The same results would obtain if the bar a was plavedwithout and to the rear of the above-specified range, as the distance between the bar and the surface of the ground would necessarily be variable, and the teeth therefore liable to a variety of accidents.

It is unnecessaryto enlarge upon the advantagesof the above-specified position of thecutter-bar, as the smoothness of cutting which it insures and the prevention of accidents which it effects are of themselves sufficient to demonstrate its utility.

What I claim as my invention, and desire to secure by Letters Patent, is

Laying the bar n, which carries the cuttingteeth, ranging with the guide-roller and per In testimony whereof I have hereunto signed pendicuiar to its side face when the axis of my name before two subscribing witnesses. said roller is parallel to the axis of the drivingwheel, for causing the cutter-bar to conform to the surface of the ground passed over, and for the prevention of accidents tothe cutting teeth, as herein fully set forth, said bar being on the gearing side of the machine.

PHILIP H. KELLS.
